Device and method for determining the length of a line

1. A method for determining the length of a line, the method comprising:

a) determining a length of a first electrical line;

b) determining an identifier of the first electrical line; and

c) determining a length of a second electrical line based on the length of the first electrical line and a starting length determined by means of the identifier,

wherein the first and second electrical lines are intended for installation in an electrical installation assembly,

wherein the starting length corresponds to an electrical line;

wherein the first electrical line and the second electrical line are formed by cutting the electrical line to length, and

wherein the second electrical line is partially preconfigured.

2. The method of claim 1 , further comprising:

identifying the first electrical line based on the identifier, wherein the starting length is determined based on the identification of the first electrical line.

3. The method of claim 2 , further comprising:

cutting the electrical line to the starting length;

associating the identifier with the starting length; or

storing the starting length and an associated identifier.

4. The method of claim 1 , further comprising:

identifying an electrical line using an identification corresponding to the identifier, wherein the identification is applied to or on a surface of the line.

5. The method of claim 4 , further comprising:

acquiring the identification of the first line or the second line by an image recognition unit; or

determining the identifier on the basis of the acquired identification.

6. The method of claim 1 , further comprising:

cutting to length the electrical line for wiring an electrical installation assembly to produce a first, excess electrical line and the second electrical line.

7. A method, comprising:

producing a first wiring set of electrical lines, wherein the first wiring set of electrical lines are each provided with at least one identification, wherein the at least one identification is associated with a starting length based on an identifier that is determinable based on the identification; and

for each electrical line of the first wiring set of electrical lines

a) determining a length of a first electrical line;

b) determining an identifier of the first electrical line; and

c) determining a length of a second electrical line based on the length of the first electrical line and a starting length determined by means of the identifier,

wherein the first and second electrical lines are intended for installation in an electrical installation assembly,

wherein the starting length corresponds to an electrical line;

wherein the first electrical line and the second electrical line are formed by cutting the electrical line to length, and

wherein the second electrical line is partially preconfigured.

8. The method of claim 7 , further comprising:

producing a second set of electrical lines, wherein

the first wiring set of electrical lines is intended for a first control cabinet and the second wiring set of electrical lines is intended for a second control cabinet,

during the production of the second wiring set of electrical lines a control-cabinet-specific plan or a control-cabinet-specific documentation of the first control cabinet is compared to a control-cabinet-specific plan or a control-cabinet-specific documentation of the second control cabinet and the electrical lines of the second wiring set of electrical lines, which are implemented identically in both the first and second control cabinet, are preconfigured.

9. The method of claim 8 , wherein electrical lines that are not identically implemented are contained in the second wiring set of electrical lines having a starting length or are omitted.

10. A device for determining the length of a line, the device comprising:

a recognition unit configured to determine an identifier of a first electrical line, wherein the identifier is an identification at or on a surface of the first electrical line,

a length measuring unit configured to determine a length of the first line;

a storage unit operatively connected to the recognition unit and the length measuring unit, wherein the storage unit is configured to acquire the identifier and the length of the first electrical line and associate the identifier and the length of the first electrical line with one another;

a detection unit configured to determine a starting point of a length measurement of the first electrical line; and

a second detection unit configured to detect an end of the first electrical line.

11. The device for determining the length of a line of claim 10 , further comprising:

a line conveyor unit configured to transport electrical lines having different conductor diameters, wherein the line conveyor unit comprises runways having different groove depths or groove widths, wherein supply of the electrical lines on respective ones of the runways is performed based on a determined conductor diameter or cross-section of the conductor.
